Military police detained 10 people in São Tomé das Letras, Minas Gerais, on the night of Saturday 22 March 2025 in an operation against street sales of food adulterated with hallucinogenic substances.[1][2][3] Those held were eight men aged 24 to 42 and two women aged 27 and 29, who were taken to the station, heard and released.[1] Those detained and the collected material were sent to the police station in Três Corações.[1][3] Police opened an inquiry and the case remained under investigation.[1][3]

The operation, called Fake, involved 20 officers working across the city.[1] The reports said the magic sweets may contain synthetic drugs, mushrooms and marijuana in their composition.[1][3] The city health network had recorded at least 13 attendances linked to the sweets, with people kept under observation reporting hallucinations, vomiting and diarrhoea.[4]

The city had warned tourists about foods sold under names such as brisadeiros, brisamelos, magic brownies, brigaconha and magic sweets, which may contain hallucinogenic substances.[4][2] The municipal alert said the products may contain illicit substances such as cannabis, as well as psychotropic medicines and hallucinogenic mushrooms.[4][2] Health surveillance said warnings were its tool because artisanal free-trade food considered low risk cannot be banned or collected by inspectors.[4] After the surveillance and police actions, sales of adulterated products fell.[4]
